LAWN-MOWER.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed September 4, 1908. Serial No. 451,670.

To all whom it may concern:

Be it known that I, AUGUSTUS L. LE VINE, a citizen of the United States, residing at Freehold, in the county of Monmouth and State of New Jersey, have invented new and useful Improvements in Lawn -Mowers, of which the followin is a specification.

This invention re ates to lawn mowers, and has for an object to rovide a simple lawn mower composed of ut few parts and to construct the same so that it may be manipulated by a person when standing erect, and to provide means whereby the cutting blade may be moved or oscillated to produce somewhat of a swinging motion to effect a reat cut with little exertion on the part of the operator.

.A- further object of the present invention is to provide a horizontally disposed cutting blade having knife ed es on twosides and to provide sprm arms between the handle of the device and the blade to im )art a greater movement to the blade to enable the same to make an effective cut and to allow the same to move with great rapidity.

Other objects and advantages will be aparent as the nature of the invention is etter disclosed, and it will be understood that changes within the scope of the claims may be resorted to WltllOlll; departing from the spirit of the invention.

In the drawings formin a portion of this specification and in which ike numerals indicate similar parts in the several views, Figure 1 is a perspective view of the present lawn mower showing the manner of holding the same when it is to be mani ulated, Fig. 2 is a side view, Fig. 3 is an our view, Fig. 4 is a perspective v1ew, Fig. 5 is a perspective view showing a slightly modified form of my invention.

Referring now more particularly to the drawings and with particular reference to Figs. 1 to 4 inclusive there is shown a lawn mower 1 comprising a relatively narrow blade 2 preferably constructed from steel and provided with cutting ed es 3 and 4 upon the ongitudinal sides of the blade. Arms 5 and 6 are provided, are formed from spring wire preferably, and have their lower ends bent as shown at 7 and are provided with e es 8 which receive rivets 9 engaged with the lade as shown. The upper ends of the arms 5 and are connected to a suitable hand 0 10. he arms 5 and 6 are dis osed at a diagonal angle with respect to the lade 2 and the handle 10 is thus located in a plane rearwardly to one of the ends of the blade 2 in order that the blade may be moved back and forth in front of the operator.

Upon reference to Fig. 5, a blade 11 is shown provided with longitudinal cutting edges 12 and 13 respectively, and at one end, the blade is forked as shown at 14, to provide spur shaped teeth 15 which may be conveniently operated to remove weeds or the like. In this form of my invention the blade is provided with spring arms 16 and 17 respec tively, the arm 16 being connected in a manner identical to that described to the arms 5 and 6 in the preferred form of my invention, and the arm 17 being connected to the blade inwardly of the said forked ortion 14.

From the foregoing it wil be seen that a simple and inexpensive device is provided which may be operated with but little exertion and which may make an effective out in an oscillatory movement of the hand of its operator when engaged with the handle of the device as previously described. The arms 5 and 6 oifer great resiliency and assist in the cutting action of the blade 2 as will be readily understood. While the arms 5 and 6 are described as being constructed from spring wire it would be obvious to form the same from any suitable spring material to accomplish the desired result. It will be seen that the arms 5 and 6 form, with the blade 2 and handle 10 respectively a frame of scalene triangular form.

Having thus described the invention, what is claimed as new, is:

I. A device of the class described comprising a cutting blade, a handle, and arms of unequal length formed from springy material rigidly secured at their lower ends to the blade and having their upper ends rigidly secured to said handle.

2. A device of the class described com rising a horizontally disposed cutting bla e, a handle, and arms of unequal length formed from springy material rigidly secured at their lower ends to the ends of the blade and having their upper ends rigidly secured to said handle.

In testimony whereof I allix my signature in presence of two witnesses.
